PI3USB14-A
Low Voltage, High Bandwidth, USB 2.0,
4:1 Mux/DeMux with Single Enable
Description
The PI3USB14-A is a 2-channel, 4:1 Multiplexer/Demultiplexer
with 3-state outputs. The switch introduces no additional
ground bounce noise or propagation delay.
The PI3USB14-A device is very useful in switching USB 2.0 sig-
nals and others that have high bandwidth (-3dB BW is 815MHz).
